1. First, verify the filter is properly assembled, has NO WATER in it and the power cord IS NOT plugged into the wall outlet.
2. Put the intake pipe with strainer into the aquarium,
3. place the small diameter breather tube/pipe so that it hangs over the aquarium rim but IS NOT submerged under the water line,
4. hold the output hose in your hand and briefly suck on the end of the hose to start the water siphoning into the filter. Just hold the output hose over the aquarium until you see the water rise in the output hose until it is close to the rim of the aquarium. Now connect the output hose to the spray bar, if you are using one.
5. Now you can plug in the power cord to the wall outlet. The filter should start working properly.
Any other questions, just ask. I own one 2229 and it is basically the same as a regular Eheim filter but it is really designed to only use bio media and not mechanical media/pads.
What size tank were you going to use this filter on?
